Title: "Exception in server tick loop" -> server crashes during startup

Version: 0.5.1

OS: Windows 7 Home Premium

Java Version: Java Version: 1.7.0_09 from Oracle Corporation

Description of Problem:

The most significant thing one of my friends was doing was saving a blueprint when the server crashed. Upon attempting to restart it crashes. It informs me of where the error report is. I cannot issue any commands (list, stop, etc). I have to use task manager to end the process.

There was something about an error that mentioned about "tics" and "entity"

[Combustion Engine - infinite use after heating up]

Title: Combustion Engine - infinite use after heating up

Version: 0.5.1

OS: Windows 7 Home Premium

Java Version: Java Version: 1.7.0_09 from Oracle Corporation (results from javatester.org)

Description of Problem:

(Playing single-player)

After using a combustion engine for a while on a refinery it ran out of fuel. I let it wind down, but each time "energy stored" counted down to where it should hit "0" it jumped back up to energy stored 6000~ish and continued counting down from there.

So, summary:

Current Output: 0.0 MJ/t

Stored: 6000~ish -> 0 MJ (counting down about 35MJ / sec

Heat: 4900 C

Energy still coming out? Yes

Fuel gauge empty? Yes

[Let me know if I may be able to find you more information]

Thanks for the help. I think the list is an excellent idea. It can be really hard to hunt down even known fixes for things when they're spread out so much. I hope something in my issue can make the list and help some other people out, too.

[[FAQ] Common Problems & Solutions]

Well, what-do-ya-know....That actually worked. (still needs playtesting to see if any features are broken, but it actually generated a world, and I can assure you THAT hadn't happened.) Thanks for the help.

[edit: btw, there were still several "this -# slot was taken already by _such and such when _this thing blah, blah, blah.

But I guess I'll cross my fingers and see if it it works anyway *shrug*]

[[FAQ] Common Problems & Solutions]

Tekkit 3.1.1 and 3.1.2 have installed and run on my Windows 7 PC just fine, but after copying the files over to a linux machine (Debian 6 Stable) I get the following errors. [sorry, I don't know how to use spoilers]

CONFLICT @ -15 item slot already occupied by net.minecraft.server.ItemBlock@1b6fea while adding codechicken.enderstorage.ItemEnderChest@893bd6

CONFLICT @ -204 item slot already occupied by net.minecraft.server.ItemWithAuxData@a6620d while adding codechicken.enderstorage.ItemEnderChest@893bd6

java.lang.IllegalArgumentException: Slot 241 is already occupied by codechicken.enderstorage.BlockEnderChes@616593 when adding ic2.common.BlockRubSapling@63a57a

I didn't even know you could get errors for negative numbered item slots. So, anyway, the exact same code works on my PC, but not the linux machine. The linux machine is running Java 7 update 5. My PC is running 7.0.0

Thoughts? (let me know if this should go in another forum thread)
